Struthers' ligament

Struthers' ligament is a fibrous band of tissue found in the human body, specifically in the upper arm. It is named after Sir John Struthers, a Scottish anatomist and surgeon who first described it in 1848. The ligament is not present in all individuals and is considered an anatomical variant.

Etymology

The ligament is named after Sir John Struthers, a Scottish anatomist and surgeon. Struthers described the ligament in 1848, making it one of the many anatomical structures named after their discoverers.

Anatomy

Struthers' ligament extends from the supracondylar process of the humerus, a small bony spur that is present in about 1% of people, to the medial epicondyle, one of the two bony prominences at the bottom of the humerus. The ligament is about 3 to 4 cm long and 1 cm wide. It is located about 5 cm above the medial epicondyle.

Clinical significance

The presence of Struthers' ligament can sometimes lead to Struthers' syndrome, a rare condition that can cause nerve compression and pain in the arm. This is because the ligament can compress the ulnar nerve, one of the three main nerves in the arm. Struthers' syndrome is usually treated with surgery to remove the supracondylar process and the ligament.
